WILLIAM HERMAN KLUGE, OF INDIANAPOLIS, INDIANA, ASSIGNOR TO THE COINCONTROLLING LOCK COMPANY, OF INDIANAPOLIS, INDIANA, A CORPORATION 0FINDIANA.

INDICATOR FOR COIN-CONTROLLED LOCKS.

To all whom it may concern:

Be it known that I, WILLIAM HERMAN KLUGE, a citizen of the UnitedStates, residing at Indianapolis, in the county or' Marion and State ofIndiana, have invented certain new and useful Improvements in Indicatorsfor Coin-Controlled Locks, of which the following is a specilication.

This invention relates to improvements in coin-controlled locks and theobject is to provide an indicator which will be controlled by the samecoin that controls the lock and thereby indicate whether the room isoccupied or open I accomplish the objects of the invention by themechanism illustrated in the accompanying drawings, in which- Figure lis a front inside view of my improved lock with the inner plate of thecase or housing removed, the view showing the bolt in its outer shotposition. Fig. 2 is a like view showing the bolt in its inner shotposition. Fig. 3 is a detail in vertical section on the line 3-3 of Fig.2, and Fig. 4 is a detail in end view of the dial shaft showing all ofthe parts in front of the bolt plate assembled thereon.

Like characters of reference indicate like parts throughout the severalviews of the drawing.

10 represents the casing within which the parts of my invention areassembled. It comprises an outer plate 12 having integral sides 11 atright angles thereto, and an inner plate 14 (see Fig. 3), which isremovably secured to the casing.

The main bolt of the lock is shown at 16, the body of which is 4flat andcomparatively thin and has its bearing against the plate 12. One end ofthe bolt is reduced in width to form a part 17 which is projectedthrough a suitable opening in the side 11. The opposite end of the boltis reduced in width to form shoulders which will limit the outwardmovement, and this end is thickened to form the part 19 which passesthrough the adjacent side 11 of the casing to engage a strikin plate(not shown). The increase in thickness at this end of the bolt forms theshoulders 21. A lever 23 havinov an upper bent end 22 is mounted on ashat 24 which shaft is supported by the two plates 12 and 14 of thecasing and is extended outside of the latter and terminates with asuitable Specification of Letters Patent.

knob or handle (not shown). The bent end 22 of the lever is attached toone end of a spirally wound spring 27, and the opposite end of thisspring is attached to a plate 28 which is secured to the plate 12 of theeasing. The plate 28 extends in a downwardly oblique direction to servethe additional purpose of a guide to direct the coins deposited in thelock, into a suitable receptacle at the bottom of the casing. The end ofthe bent portion 22 of the lever 23 is held in constant contact with theshoulder 21 of the bolt by the spring 27. The lower end of the lever 23is continued below the pivotal point 24 to contact with a shoulder 25formed in the plate 28 whereby the movement of the lever in thatdirection is limited.

30 is a coin-chute, the lower end of which discharges within the casingabove the bolt 16. Mounted on the bolt 16 so as to be directly under thedischarge end of the chute 30 when the bolt is in its outer shotposition, is a continuation 33 of the chute, the upper end of which willpreferably be expanded into a funnel to insure the delivery of the coinfrom the upper section 30 to the part 33. An outwardly and upwardly bentplate secured to the casing has its upper edge extending across thedischarge end of the chute extension 33 far enough to prevent thedischarge of a coin from said chute eX- tension while the bolt is in itsouter shot or locked position. The chute extension 33 has a transversenotch39 in its lower end to permit the upper end of the lever 23 totravel through said chute extension except when prevented by thepresence oi a coin 37 therein. When t-he notch 39 is closed by thepresence of the coin in the part 33, the lever 23 by contact with thecoin will shoot the bolt 16 inwardly of the casing thereby unlocking thedoor, and as soon as the bolt moves far enough to cause the coin to passthe end of the bent plate 35, the coin will be 'tree to drop by gravity,and. should it fall too far to the front ol the casing it will bedirected to the rear by the oblique plate 28. The throw of the lever 23is arrested by the contact of its lower end against the shoulder 25 ofsaid plate 2S, and a person manipnlating the knob on the shaft 24 willinvariably release his hold upon the knob at the arrest of the lever 23by contact with shoulder 25 so that if the coin has not been previouslyreleased, it will be upon this occurrence and will drop to the bottom ofthe casing. Y

42 is a key mountedin the lock-casing so as not to be removabletherefrom, and having its stem extended outside and squared to fit thesocket of a removable extension carried by a porter or other attendantwho has occasion to Vfrequently enter the room.

Supported by the lock-casing, between the bolt 16 and plate 14, parallelwith the latter, is a plate 43 having a round hole to receive thereduced end of a dial-shaft 44. Mounted on the shaft 44 is a pinionWheel 45 having a blank portion 46 to limit its rotation. The shaft 44extends through the plate 14 with a sliding fit. Loosely mounted uponthe shaft 24 is a plate 48 having a circular segment of which the centerof shaft 24 is the axis,rprovided with teeth 49 to engage the teeth ofthe pinion 45.V Lugs 50 atV each end of the toothed segment help tolimit the travel of the plate 48. y

Mounted Von the dial-shaft 44 and Voverlapping the pinion 45 and toothededge of plate 48 is a washer 52 which is held yieldingly against both ofsaid parts by a spring 53 wrapped around the shaft- 44 and locatedbetween the washer 52 and plate 14. By this manner of 'applying thespring the various movable parts are held in proper operative relationwithout binding, thereby leaving the dial-shaft always free to turn,which is essential for a reliable indicator.

54 is the dial bearing the proper inscriptions as Occupied and Open, andhaving a stem 55, here shown as square in cross section, to it in acorresponding longitudinal opening in theshaft 44.

Located between the plate 43 and the bolt 16 is abentbar, one end, 56,of which, extends outside of the lock-casing and is provided with a knob57. The extension 17 of the bolt 16 has a longitudinal slot'58 throughwhich the knob 57 is passed and because of the slot 58 a limitedmovement of the bolt 16 is permitted without moving the bent bar orlever. After the bolt 16 has been shot inwardlyV to the position shownin Fig. 2, and the indicator mechanism moved substantially to theposition there shown, the bolt will'be returned by the action of thespring 27 through leven23, leaving the indicator mechanism undisturbed,and the coins inserted in the chute 30 while the room or booth isoccupied will not aect the adjustment of the parts of the indicatormechanism. The end of the inner portion 60 of the bent bar terminateswith a lateral extension or bent part 61 which passes through a slot 62in plate 48 concentric with shaft 24, and the edges of this part 61 willpreferably be notched to engage the plate 48 on each sideof the slot toprevent the withdrawal ofthe part 61 except when the Vlatter is turnedlengthwise of the slot, which does not occur while the parts areassembled in the finished condition. Y

When the person in the roomor booth desires to retire from same, he willunlock the door by an outward movement of the knob 57. The first periodsof this movement will be permitted by the slot 58 without moving I thebolt 16, but when the outer end of said slot is reached, the bolt willbe moved so as to unlock the door and at the same time the end 61 of thebent bar orl lever 56-60 will return the segment-plate 48 to theposition shown in Fig. 1, which will rotate the shaft' 44 and expose theOpen inscription on the dial. The dial will be set to the position ofOccupied by inserting a coin in chute '33 and moving the plate 42 bypressing the coin Vagainst it by lever 23 and knob of shaft 24, but theplate 48 will remain in the position thus given it until Vit is movedback by the above outward movement of knob 57 and lever 56-60.

Having thus fully described my invention, what I claim as new and wishto secure by Letters Patent of the United States, is
